buoyant

s to sink or rise by controlling the amount of water in their tanks, thus changing their overall density. Hydrometers and Density Measurement Hydrometers utilize buoyancy to measure the density of liquids: The device’s weight and shape are calibrated so

ed in water. The density of aluminum is 2700 kg/m³, and the density of water is 1000 kg/m³. What is the magnitude of the buoyant force acting on the cube? Solution: Calculate the volume of the cube: \( V = s^3 = (0.5\, \text{
